Plant Traits in Fig as Indicators of Resistance to Shoot Borer, Dyscerus? Fletcheri Marshall (Coleoptera: Curculionidae)

A comparative study was conducted on fig (Ficus carica L.) cultivars Deanna and Poona to test whether antixenosis due to plant traits was at least partially responsible for a differential susceptibility to the shoot boring curculionid weevil, Dyscerus? fletcheri. Field evaluation revealed significan...

Deanna, which was highly susceptible to shoot borer. However, latex-flow index was significantly higher in cv. Poona that was resistant to the borer.
